This invention reiatee to controlling de- `vices for fahrieprintingmachines of the type having a pinraiity of 'printing ineinherss or apinraiity ci siete yof printing members for printing diiierent designeon the fabric,r

andin (which the eontroiiing mechanism iior the printing members ie eoarranged that the printing' niemhere are eaneed to auto# `naaticaiivoperate in a prearranged order with relation to each other, and providesmeans adanted to vary the order of .the operation o'it the printingmembers Without stopping; the machine.

An object of our invention is to provide4 avcheap and efficientcontroiiing mechanism ot this character which can readily he applied tomachines of this type, and partielliarly to hiocienrinting machines. fornrintmg ping the machine.

Another object of our invention is to proenge ci' diiierentiengthsWithout stopswitches will be arranged in threel Vide a device of thischaracter in which the mechanism is set so that rugs of a predeterminedlength are printed successively, each having a field and a surroundingbor der portion. These rugs comprise end sections consisting of bordersextending the full Width and a plurality of intermediate sectionsconsisting of a body and side borders. Assuming that the machine hasbeen set for printing rugs nine feet long. and there should be a badspot on the fabric to be printed, if the order could not oe changed, oneentire rug, and perhaps two entire rugs, would be damaged. By ourinvention we are enabled to print a rug of different length than that onthe run which we are making, so as to bring the bad spot at the end of arug, and then start a new rug immediately beyond the bad spot, so thatonly the section of fabric in which the bad spot appears will be wasted.n other Words, if we were printing rugs nine feet in length and a badspot should appear on the end border section of the rug being printed,we can throw the end border printing blocks into operation one sectionin advance, so that the rug printed will be seven and one-half feetlong, and then throw in another border section immediately beyond thebad spot which will form the end border of the next rug.

In the specific forni of printing machine and controlling mechanismshown and described, we obtain this` object by providing anelectromagnetically controlled latch for etch printing block, and inwhich the circuits for the magnets are closed by means ot' switcheswhich are actuated by selectors. The switches are arranged in groupsabout a rotatable drum, and each switch is provided with a movablemember having one or more actuating lugs lying adjacent to the drum, theactuating lug or lugs of the diiferent groups lying indifferent planes.Ii' the end borders of the rugs only one-half the Width of the printingblocks, the switches are arranged in two groups, one group controllingthe end border blocks, and the other group controlling the iield andside border blocks. It, however, the border on the rugs is as wide asone otl the printing blocks, the groups, namely, a group for thestarting of the border, a group ior the finishing of the border, and agroup for the lield and side border sections.

Y' he drum adjacent to the lugs of the switches is arranged lo `berotated in timed relation to the fabric passing through the machine, andthe selectors are each provided with an actuating lugfor actuating theswitches while passing the lugs con'- nected `to thc movable switchmembers. The selectors are slidably mounted on the drum and are arrangedto move transversely thereon, in order to permit the lugs on theselectors to be shifted laterally into the path of the lugs on thediilf-rent groups oil" switches.

Surrounding the drum arc circular guides or selector grooves in whichthe lugs on the selectors move ii a prearrrmgcd order to actuate theswitches of' the various groups whose lugs lie in their path oi' travelor in the same vertical planes.

In this type of machine, the printing blocks are spaced apart so thatduring one fall of the blocks, alternate .sections ol the fabric are inposition to receive impressions, and at the next fall of the blocks theother alternate sections are in position to receive impressions, andwill be printed upon by the blocks which are over sections which are toreceive .impressions by the blocks. The machine shown in the drawings isprovided with ten printing blocks and twenty selectors, so that eachselector moves in unison with a section of the fabric during its passagethrough the machine, and actu-- atcs the switches in its path to close.the circuit through the electromagnets and preventI theprinting blockcontrolled thereby from making au impression on the section of thefabric controlled. thereby when under said block.

As above stated, the printing on each section of the fabric during itspassage through the machine is governed by a selector, and after a givensection has passed beyond the last printing block, said selector willhave made a complete cycle of switch mechanism and is available forgoverning the work on another sectiony of the fabric passing into themachine.

The precise nature of our invention will be best understood by referenceto the accompanying drawing. which will now be described, it beingpremised, however, that various changes may be made in the details oiconstruction and general arrangement of the parts, without departingfrom the spirit and scope of our invention as delined in the appendedclaims.

ln Fig. l of the drawings, the reference character 2 designates thefabric passing through the machine. and which, 'for the sake ot'clearncss, we have divided into sections e, er, er. 2e, 2f, 2g, ai, eal. am, 2n, 2o, 2p 2q 2r, Qs) 2e* 3A, 3A7 3137 gn, nd 3c 3C, designatethe printing blocks. l'n the first group, 3^ are the blocks for printingthe end border sections, such as Q, 2, SZ

and 2t, while the blocks 3B form the second,

group which are for printing the field and side border sections betweenthe above nientioned border sections. idle blocks and are not used forprinting a design such as shown in Fig. 1.' ie, 4^, e'l-B, 4B, and 4to,4C are the solenoids for actuating The blocks 3C are selector, as

- linnesco the electric switches for control-ling,n the printing blocksott the ditlerent groups.

,Each of these solenoids has a core .5, which nets is closed by means ofa switch having;

switch-'blades 9, a movable switch .member 10,.- having a knife 11,connected thereto, each imite being arranged to enter between its blades9 "to close the circuit through one of the solenoids 4l.. ltlach ofthese switch members 10 is provided with a lug 12, Which is arranged tobe engaged by a lug' on a hereinafter described., to close the circuitthrough the switch. ""Dne pole of each 'oit the solenoids is connectedto a line 13, leading from a source ot energy 14p the otherV line 15from the ,source of energy 14e is connected directly, to one et theblades 9 oi' each of the switches. r.the other blade' 9 of each of theswitches isv connected to the other pole of its solenoid, so, thatWhenthe knife of the switch engages the blades thereof, the circuitthrough its solenoid Will be closed, which Will,` in turn, actuate thellatch and retain the block controlledthere by in its elevated position.

16 designates a drurn which, in Fig. 1, has been spread out in a plane,and which is provided with. twenty transverse grooves for thereceptionot selectors 179', 17", 17, 17d, 17E, 17f, 17g', 17, 171, 17j,17k, 17, 171, 17, 17, 17p, 17, 171', 17S, 17H. each selector beingarranged to control the switches for its particular section ot fabric.'l`he 1 lee tors` are each provided With a projection 18, which isarranged to pass at one side or the other of a dividing plate 19 and tobe shifted from one position to another position. by means of a switchcam 20, which is located over ythe selector 17 in the position 'shown in1., so that the proiection on this selector will be shifted to the lower.side ot' the division .plate 19, lfor the purpose hereinafterdescribed.

In F.' ,l 1, the printing blocks 3", 3^. are arranged to print the endborder sections.

"while the 'printing blocks '3B printthe field and side bordersectionsbetween the border sections which forms the ends of the rugs;

the blocks 3C Abein@0r normally held out. of action by the hand latches21. rll`he project/ions 12 on the movable switch members l() for thesolenoids 44' are placed iii the space above the division plate 19, sothat the)l will be engaged andhll of' the switches closed when aselector is shifted so that its projection 'is above ,the divisionplate; while the projections 12 'on the switches for the group otsolenoids L1 are below the division plate, so that their switches willbe closed by projections on the selectors below the division plate. Asthe last two printingblocks are not used when printing a design such asshown in Fig. 2, the movable switch inem bers therefore are removed, sothat the circuit through the solenoids will not be closed,

as the blocks are heldout of action b v means ot" the hand latches.

The niaehineas set up in Fig. 1 is designed to print rugs in 'which'theborder sections have red, blue and bla-ck blocks, while the lieldsections have green and brown blocks, and the side border sections havered, bine and black blocks to contorni to the transverse bordersections. The red blocks of the border .sections are printed by thefirst block 3A (which is marked Red) asshown on section 2, and otterthis section has passed beyond the third printing block 3A (markedBlaclt) the end border section w ill be coinpletefhes shown in thesection 2h. As this section has now been conipleted. none of theremaining blocks will make an impression thereon. The field .and sideborder sections vvhile .passing under the group oi printing' blochs 3Awill not receive any impression, bnt the border` portions thereof willbe. printed the first three blocks 3E (which are marked Red, Blue andlilaclrlh so that the border portions on these sections will be printedwhen they section 2m. The brown and green bloei-:s in the tield sectionswill be-printedby the last two printing blocks in thegroup 3b, so thatall or' the sections will be completely printed when they reach theposition `oli the section 2q. The machine when set np to printrngs, suchas shown in this ligure, arranged to shii't the switch cani Q() from itsupper po sition to the position shown in the drawing; every sixth stepinoH ement ot 4the fabric, so as to print rugs ha.. g live iield andside border sections. as shown at the leiit end ol: the fabric passingthrough the machine. lt a section should l vak had spot such shown at Xin sectie l thi-i switch` cain 2t) is shifted one step. t 1er so toshift one oi" the selectors. which, in `this cada, has been selector 17.to the lower pos-limo, so that n n rtsi reV .vhen passing under l havereachedthe position or the the blocks 3^ will. be permitted to descendvblocks 31" wheat-,he section 2@ passes under them, so that thisrug'between sections El and Q will have only four field sections. Inthis construction, the section 2b will receive impressions from thevarious held I above the division blocks, as its selector is in theupper groove. but in order to start a new rug. the selector 17al hasbeen shifted to the lower groove, so that the section 2 will receiveimpressions from theI end border blocks in suf-cession as it passesunder them. while the field and side border blocks 3B will be held outof actionin succession while the section 2 of the fabric passes underthem, as the projection 18 of the selector' 17 will close each of theswitches for the solcnoids 4B.

It .vill therefore be readily understood that if it had been necessaryto print this rug with tive field sections,4 two rugs would have damagedspots therein, while by our invention, the rug within sections 2c and 2"will be slightly shorter than the other rugs without any imperfections,and therefore, the. only loss will be one-half of section 2, section 2b,`and a half 4of section 2". If this damaged spoil-"should only eXtend asfar as the damaged spot Y on section 2b, .the border blocks could bethrown into action to print on this section, so that only one` sectionwould be lost, namely, half of sections 21J and 2c.

In Fig. 1, the machine is in such 'a position that the blocks are readyto descend, and those that are latched will be held in their elevatedpositions, while those that are free to descend will impress the fabricas indicated in dotted lines on the sections belowthe blocks. Therefore,sections 2*, 2, 2p will be printed upon, the impressions being made bythese blocks being shown in dotted lines.

In the foregoing description, we have described how the mechanism is setup for printing rugs having three colors in 'the border and two othercolors in the field. It will- Ibe understood, however, that lthe machinecan readily be set up for printing diderent designs and differentcolors, but. in all cases theprojections 12 for actuating the movableswitch members for the end border blocks will be placed above thedivision plate, while those for actuating the movable switch members forthe switches for controlling the lield and side border sect-ions will beplaced below the division plate. Therefore, it isronly necessary toplacethe selectors for the end border .sections below the division plateand those for the field and side border sections cam 20. This cam 20 isnormally in the position to shift all of the selectors above thedivision plate, andv is only shifted when it is desired to print an endborder section and is then returned to its normal position.

In the' machine shown in Figs. 4 to 30,I

the printing blocks 3, which are of the usual character, are mounted onslide members 22` which are arranged to move between guides 23, and areprovided with rollers 24, which manner.

plate by means of the are engaged by cams 25, to raise the blocks totheir elevated positions during` each step movement of the fabric, topermit the paint pans 26 to pass beneath them to ink the blocks by meansof theusual rollers. These paint pans are all connected together bymeans of links 2T, in the usual manner, and are adapted to be moved backant forth by mechanism well known to those, familiar with the art duringthe time that the fabric is fed forward by the belts A. The cams 25 forelevating the printingblocks are mounted on shafts 27, there being a camon each end of said shaft for actuating its printing, block. Theseshafts are rotated in the usual 30 is a casing which is located. at theside of the printingr machine at the operators stand, and which casing,`incloses the switch mechanism for the solenoids. Rotatably mounted inbearings in this casing is the vertical shaft 3l, which is provided witha worm 3l, which meshes with a worm wheel 32, on'a horizontal shaft 33.This shaft 3l is provided with a bevel gear 3l at its lower end whichmeshes with a similar bevel gear 35 on a transverse shaft 3G, which isdriven by means of a bevel gear 37. which meshes with the bevel gear 39on a shaft 29. This shaft 29 is connected to the shaft 27 by means ofbeveled gears 28, so that `the shaft 38 will be rotated in unison w' l1the shafts 27, which actuate the print-ing blocks: and as all thedevices for tetu-ating the switches, as hereinafter described, areoperated by the shaft 31, it will be readily understood that all theparts will be in timed relation with the printing machine.

Connected to one end of the shaft and within the casing 30 is theselector drum 16, which is provided with a plurality of transversegrooves 40, for the selectors 17 to 17. Surrounding the selector drum 1Gis an annular casing 4l, in which is mounted the die vision plate 19,there being; an annular groove on each side of the division plateinwhich the lugs or projections 18 of the selec tors travel. Mounted onthe exterior of this annular casing 41. are the staiiomxrv switch blades9, and mounted on pins` l2 are the movable switch members 10, having;`the switch knives 11 at one end and actuating projections 12 at theother end. The actuating projections on the switches for controlling thecircuit to the solenoids for the latches for the field and side borderblocks extend on one sido of the division plate, while the projectionson the switches for controlling the circuit to the solenoids for the .ortrein the time that ay section of -fabric neen make a completerevolution in twenty steps,

passes from the position 2a oi' Fig. l to the nextposi'tion'beyond 2.' Y

Slidably mounted in a groove in the casing il between the endsfotthedivision plate l`9`is a bar 43, which carriesthe svvitchcani 20.:-'llhis bar extends vlaterally from 'the @drinn and is provided with arelier 44e at the yother end thereoii.- `This roller le rests in a ,camgroovediforined inthe end of a lever is `in the dottedline position, itwili shiftV the next selector passing this point into the l' f `groovecontaining the projections on the ends of the movable members oi the'switches for closing the circuit to the solenoids to loot'. the blocksfor printing; the -tield and side borderv sections. Movably mounted onad justable guides 4S, secured to the trarnel 39 is a slide 49, havingratchet teeth 50. 5l is a1 spring-actuated pavvl connected to a. slideblock fila, actuated by a pit-man 52, which is connected to a crank pin53, on the end of the shaft 31, so that the slide e9 will be advancedthe distance of one tooth for each revolution of the shatt- 31, and `toreach movement of the Yfabric under the printing blocks.

Pivotally connected at'lto the frame 39 is a retaining pawl 55, forretaining the slide 49 in the'position to which it has been shiited bythe pawl 51. ltivotally mounted on the same pin on which thefpa'wl 55 ismounted is a releasing lever 56, which is normally held in its inactiveposition (that shown in Fig. 11) by means oit a spring 57, there being asimilar spring-under this spring 57 for retaining the pavvl 55 in engogement with the ratchet teeth 50. This pawi releasingzlever 56 isprovided with a downwardly extending projection '58 which lies in thepath oi the retaining paivl 55, and also in the path of a retainer 58awhich also l'iesv'in the path. ofthe dinger i7 on the lever liti. 1

The slide 49 is provided with a cylinder 59 having a piston 60 thereinwhich is connected to one end of a piston rod 61. This piston rod 6-1 isiixedlyconnected to a projection on the frame 39, so that the cylinder59 'is adapted to slide over'tbe rod. Surroui'ldinp, the piston rod (iland Within the cylinder is a `coiled spring 62, which en gages one endot the cylinder and the piston for moving the slide to the lett when thepawls are released, and also tor retaining the slide against theactuating" pawi 5l or the retaining pafwl 55. 63 is a cock in the end otthe cylinder 59 Afor controlling the exhaust ot the air from thecylinder yand thereby controlling the speed of the return movement ofthe slide. r

' Connected to the'slide/it) is an actuating; bar gnide (iii, having apluraiity of recesses which form guides for the actuating bars ttipandwhich are arranged to' be raised and lowered into and out of the path ofthe end oi the lingerie-.7" on the lever 46 by means ot keys G6. Each oithe actuating' bars G5 is provided With a pin G7 which is seated in arecess 68 in its hey 66. rlhese keys are pivotally mounted on the shaftb9 on' the slide ett-),thearrangement beingr such thatvvhen the keys arethrown to the position shown in 17 the actuating; bars will be in theirelevated positions, but when either ot the keys is moved to the right adistance 4ot approximately ninety degrees the actuating bars will bethrown to their lower positions, as shown at G5 in Fig. 6, so that the,bar which has been thrown to this position will be in the path et the'ii-nger i?. Each ot the actuating bars 65 is also provided with alocking projection 70 which is arranged to poss over a guard 7l whenthebars 'are in their raised positions, and to pass under said guardwhen. in their lowered positions. This guard is connected to the end ofa bracket "(551 which is secured to the trame 39 and is provided With anopening for the reception, ot the pivot pin for the lever 46. IThisguard is placed im.

linediately above theend ofthe finger 4'2", so "that theoperetor cannotactuate 'a hey 66 when its bar is in a position to engage the iinger4t?.

rthe retainer 58 above described .is connected to a slide 'f3 which ismovably mounted in the frame 39, and is arranged to be ,shifted in onedirection by the tinger e? and in the reverse direction by a projectionZ4 connected to the slide-cylinder 59.

'lin the operation oi' theinacliine the drum lo is continuously rotatedin timed relation. to the movement of the fabric under the printingblocks, and es the switch cam 2O normally occupies the position shown inFig. l1 the selectors will pass into the groove in which the projectionson the switches for closing the circuits to the magnets controlling theend border latches entend. The actuating bar 65' for making the-` properlength rug is thrown downward as indicated at G5* in Fig. 6, and theslide t9 is advanced one step in each movement ot' the machine. Whenthis bar is moved to the position Shown in Fig. 8, it Will be in enragement with thel end ot the tingen et?, and

on the next movement it will shift the line illu ioA

into the other groove, to print an end border section. On the nextadvance of the paw] 51 the finger 4-7 will be advanced to the positionshown in dotted linesin Fig. 11 and full lines in Fig. 10, which willshift the retainer 58 to a point. where it will pass the end of theprojcction'S on the paWl releasing lever 56, which will throw theretaining pawl 55 out of action. and `also throw the end of thereleasing lever into the path of' the heel of the pawl 51, so thatshortly` after this pawl is advanced beyond the position shown in Fig.10 it will be thrown out of engagement with the teeth 50 with which itis now engaged, and assume the dotted line position when it hascompleted its full throw. The slide is non7 :treeto return to itsstarting point, as both pawls have been disengaged from the natchetteeth.' Just before the slide reaches its starting point, the projection7 -1 on the slide will engage the retainer 58a and shift it from theposition shown in 10 to that shown in Fig. 8., which will again permitlthe pawls to become active to shift the slide 49 to the right. if it isdesired to make a rug shorter than that set for the regular' run, it. isonly necessary to throw down an actuating bar in advance of that shownat 65X in Fig. 6. and after the short length has been completed to cutout a bad spot, this bar is raised to permit the machine to make theregular length rugs.

In Fig. 1..we have shown a compound latch lever 7 and 8 connected bymeans of a spring for retaining the printing blocks in their elevatedpositions. This showing is merely diagrammatic, the actual arrangementbeing shown in Figs. 4, 30 and 31. In these figures there is a throughshaft 75 journaled in the frame of the printing` machine` there beingone such shaft for each printing block, and connected to the end of thisshat'tI is a latch lever 76. Connected to the intermediate portion oithe shaft 7 5 is a lever 77 which is connected to a link 78slidablyniounted on a connecting rod 79. rIhis connecting rod 79 isconnected to a core 80 oi a solenoid Sisupi'iortcd on the trame of theprinting machine. Surrounding the connecting rod 79 and engaging washeror nut 82 on the end of the rod 79 and a boss 83 on the link 78 is acoiled spring S4. The arrangement is such that when the solenoid 81 isenergized the core 80 will be moved downwardly against the action of thespring $4 even though the latch member 76 would be in engagement withthe plane surface ot a latch lug 85 on the slide 22 during its upwardmovement. As soon as this lug 85 passes tho latch 76 the spring 84 willexpand and throw the latch into position under the lug 85 to prevent itsprinting block from falling after the high spot of cam 25 passes beyondthe roller 24. In order to release the latch after the circuit has beenbroken we, connect a weighted lever SG to the shaft. 75, which will movethe latch 76 from under the projection 85 when the circuit to thesolenoid has been broken.

n Fig., 1 we have shown an auxiliary latch 21 for locking the idleblocks out of action, but it will readily be understood that the latches7 6 may be. moved into position to retain the blocks inthe-ir elevatedposition and locked there by any suitable means.

In the foregoing description we have described a machine for making rugsin which the end border sections are cut along the center, so thatone-haltl of each end border section forms one end of a rug, or in otherwords, the width of the horder on each rug is only one-half of the widthof thc printingr blocks. if it is desired-to make rugs having borders ofa width equal to the width of a printing block,. it will be necessary tocnt two Sets of printing blocks for printing the end borders. and oneset of blocks for printing the field and side border. The one set ofborder blocks will print the beginning oi the rug while the other setwill print the ending of the rug.

n Fig. 2, we have diagralnmalically illustrated such a machine, in whichthe two printing blocks 3D are adapted to printy the border at thebeginning of the rug, the blocks 3E the bordel' at the end of the rug.and the blocks 3F print the tield and side. bordel'. The four blocks' BUare idle blocks and are not used for printing a rug such as shown inthis ligure, which only has two colors. In an arrangement of thischaracter, it is necessary to have three grooves surrounding the drum 16for the switches, and when a selector projection 'is in the lower groovethefborder printing blocks for the beginning of the rug are permitted tofall upon a Section, when a selector projection is in the central groovethe border blo .cs for printing the end ot the rug are permitted toi'all. and. when in the upper groove tho blocks tor printing the held and side bordelare permitted to fall.

The actuating mechanism for the lever 4G for shifting the switch camwill be similar to that t'or actuating the lever shown in Fig. 1l, withthe exception that the linger 47 will be advanced one step 'from that.shown in Fig. l1, whereinr the cam 45 on tht` ond ot' the lever 46 willbe advanced an :ulditioual step to that shown in the Qther figures oithe drawings. The normal position i`or the cam is that. shown in t'ulilines. and when ti f' linger is moved to the first. dotted linepositionv tbc switch cam :2O will be shifted to the central groove tofinish a rug. when moved to the second dotted line position the switchcam 2O will be moved to the lower groove to nascono start a rug, andwhen .moved to the third dottedfline position` the slide `will hevreleased. 'lt 'there should be a bad spot and it next to printthobeginnning; section ci the Abordel.' for the next rug, thclevcr lo canbe held ,in its 'full thrown.,position-by hand.w '.lhis Will hold` theratchetlmechanlsm out 'ot notion and prevent theslide'lf from return-;ingto its.,starting point, desiredthe `slide itselfA may he heid inthis position.

in this iigure cachot theswitch members is provided. with twoprojections i2, so that a selector `in either groove will operate twosets ci' switches, or, in other Words, ii' a selector is in the upperfgfroove it will closetheswitches for printing both endnborder sections,it in the central groove it will close the switches for controllingtheiield blocks andthe blocks for beginning' a rug, and it in the lowergroove it Willlclose vthesvvitches ttor the fieldbloclrs and the'bloclrsfor print lingthe end ci the rug.

lt is sometimes .desirable to prevent ell ot' the blocks from descendingon one or more sections of the fabric passingD through the machine,which may be when there is a bad spot in the fabric, or when e nei/v7roll ot' fabric has been clamped to the end of Va roll just passing'through the machine. We accomplish this in themanner shown in Fig.

,3, in which the machine is set up ttor printonly 'one-halt the,V Widthoi the printing blocks, suchA as shown in Fig. i. ln this ligure, Wehave also shown three grooves Jrior the switch `and ,selectorprojections, and [provided each of thel switch members with twoprojections. The central and upper grooves are precisely the '.sa'me asthose shown in Allig. l, and, the upper projections on the switches arelocated. in the same position as those in Fig. l. Each yof the switchmemhers `l0` Lis ,provided 'with an additional projection inthelowergroove, the arrangement `losing such that if a selector is shifted sothat its projection passes Ain the lower ,'gioove, such as i7@ thisyprojection will ac.

tuate each. ofl the switches in succession as it passes the, projectionsthereon, and thereby successively lock each printing block and preventany 'of them from' making an impression on the section of fabricrepresented `by this selector. The lever i6 in a construction of thischaracter is provided with a cam precisely the same as 'the ca'm 45 otli i'. l1, with the exception that it is provided with enadditional step45h at the end thereof, as `shovvn in Fig. 29, end When mg a rug; in two"colors, Whose border is WIW it is desired to throw a selector in thelower groove `atter printing` hoi-der section to avoid printingu on ahad spot or prevent the printing" loloclrs from descending on the` clampwhich seciues the ends ci" two rolls opffffabric to each other, ythelever to 'pushed to its extreme positionby'liand im mcdiatelv at'tcr aselectorfior 4printing; an end border section has been thrown into theend border groove. rThe lever /id is held inthis position until afterthe desired numlierforff sections which are not to be printed have' paed into the machine, audit is then n p a selector into` the contralorend runder groovmand then released to permit the machine to operate toprint rugs of the n'edetermined length.

The advantages of our invention 'will he apparent to those skilled inthe art.,I since it provides a multiple printing` member printVv ing' malaine by means of which, by the simple co itrol of selector' mechanism,the length ot the rug or other design can be readily chan ed, therebyenabling' the loss by Waste to e reduced to a minimum, as Well asenabling the ready changing for any purpose in the length oi' the designbeing printed. The invention is particularly `advantagemis in connectionwith multi color design printing1 since it enables the various printing`mein ersnccessary in this work to be reedily and easily controlled. Theselector Amechanism itseli' is simple in itsfconstiuction, arrangementand operation and capable of being readily operated. l-'iy providing acontrolling device, or selector, for each 'section oi' the fabricWhichfis at any given time under the operation ot the machine, We areable to simultaneously Werl; upon a plurality of different sections andyet perfectly control the operation ot the printing members on each.section to vary the length of, the design being printed. as mayloe-necessary with the ditlie-rentconditions of operation `as theylarise.

lt will, of course, be understood that the particular machine -which isherein shown and described is illustrative only, and that our inventionset forth in our broader claims is capable of various and Widely'ditoithe selector mechanism and their con-1 trolling devices.
